My 4G works but still can’t send MMS
You need activate 4G by sending SMS to some number. I don't remember...
I’ve moved to Lebara 2 weeks ago and internet is not the greatest. With 2 bars of 4G I can’t even open basic websites nor use google maps. Also, MMS don’t work for me and ‘they are investigating’. Never had similar issues with my previous network so will be looking for a network using O2.
Unfortunately unlimited EU minutes plan costs 15 GBP, not 8. Anyway, thanks for link mps01!
